Identify the correct statement w.r.t floral rewards.

In some species floral rewards are in providing safe places to lay eggs; an example is that of the tallest flower of Amorphophallus (the flower itself is about 6 feet in height) is the correct statement.
Whereas edible pollen grains and nectar are the floral rewards commonly observed in zoophilous plants.
A relationship exists between a species of Pronuba moth and the plant Yucca where the moth deposits its eggs in the locule of the ovary and the flower, in turn, gets pollinated by the moth.
Night flowering plants are pollinated by Moths. They are highly scented, and their flowers are generally white coloured.
